Acute renal failure Algorithm
Please review definition and pathophysiology
Assess for the presence of major risk factors:
Advancing age with CHF, DM HTN
Pre-renal:
Intra-renal
Dehydration
Acute tubular necrosis (ATN)
Hypovolemia
Autoimmune kidney disease; SLE.
Sepsis
scleroderma
Hemorrhage
Diabetic nephropathy
Burns
Hypertensive nephropathy
Trauma
Infections
Serious illness and surgery
Hemolytic uremic syndrome
Low cardiac output syndromes
Nephrotoxins; contrast dye
ITP
YES
NO
Are Risk
Factors
Present?
Initiate client education for Health Seeking
Behaviors to identify:
Screening urine for microalbinemia if
compelling med history is present; HTN,
DM, autoimmune disease, etc
 Don’t abuse alcohol or drugs especially OTC
drugs that have a nephrotoxic profile
 Avoid long-term exposure to heavy metals,
such as lead, as well as to solvents, fuels
and other toxic substances.
 Ensure adequate hydration
 Use appropriate hygiene NO
to reduce risk of
infections
 Encourage routine disease screening and
periodic physical exam according to risk
profile
 Instruct client in s/s of risk factors to report
 Teach client s/s of acute renal failure to report
Box 1
Negative
Assess for s/s of ARF:
 DecreasedYES
urine output; Nocturia
 Swelling/edema
 Weight gain
 s/s of fluid overload; CP, SOB
 hypotension, hypertension
Are positive findings
present?
Initiate the plan of care for a Risk for Ineffective Therapeutic
Regimen management:

Stable, newly
diagnosed?

Potentially
unstable?
Follow plan of care for PC: ESRD
Post-renal
Obstructive uropathy; Ureteral,
bladder outlet
Prostate gland disorders






Teach client about course and progression and the potential
complication of ESRD if ARF is not corrected
Explain diagnostic testing if indicated definition and interpretation of
results; bloodwork such as creatinine, and calculation of GFR;
urine testing such as creatinine clearance and microabumin,
kidney radiographic procedures; IVP, KUB, renal ultrasound, CT
scanning, biopsy
Assist client in strategies to reduce modifiable risk factors
Teach client strategies to protect kidney from injury, nephrotoxin
avoidance (radio contrast agents, aminoglycosides,
NSAIDs) and infection protection
Instruct in use of medications for acute and chronic use; dopamine
for decreased perfusion, ACE inhibitors for nephroprotection
Review diet and hydration according to disease state, discuss lower
protein, sodium and potassium as ESRD develops
Review renal replacement therapies in the presence of ESRD or
unresponsive ARF; indications and considerations such as
hemodialysis, peritoneal dialysis and transplantation
Patient teaching from box 1
Box 2
OUTCOMES/BENCHMARKS:
Urine output > 30 ml/hr
Creatinine and GFR WNL for age, no microalbuminuria
No edema, weight gain, s/s of fluid overload such as DOE; SOB,
140>SBP> 100, 100>HR> 60 no dysrhythmia
PC: ESRD
ASSESS s/s of renal failure
 Decreased urine output; Nocturia
 Swelling/edema
 Weight gain
 s/s of fluid overload; CP, SOB
 hypotension, hypertension
Assess for contributing factors:
Pre-renal. Intra-renal and post renal
DO
Protect kidney from further harm
 Discontinue or adjust any medications that
require adjustment for renal dosing
 Relieve obstructive uropathy
 Control autoimmune exacerbation
Ensure adequate renal tissue perfusion
 Reversal of hypovolemia by rapid fluid infusion
often is sufficient to treat many forms of ARF.
Monitor for fluid overload
 Administer prescribed diuretics to promote urine
output if indicated and dopamine agents by IV
infusion to ensure renal perfusion as ordered
and monitor effect
Prevent electrolyte and acid base disturbances:
 Avoid agents that exacerbate hyperkalemia and
hypernatremia
 Renal replacement therapy may be required
Provide renal replacement therapy as ordered
and monitor effectiveness
 Acute H/D, PD, and CVVHD
MONITOR
Monitor for hypo/hypertension, tachycardia,
tachypnea,
Monitor hourly I/O for urine output < 30 ml/hr
Monitor for rising serum BUN & creatinine
Monitor urine for presence of protein
Monitor daily weights
Monitor for contributing factors
Monitor labs that indicate hematologic etiology;
Hemoglobin, hematocrit and platelets
Monitor labs indication low cardiac output syndrome;
echocardiogram, chest x-ray, serum BNP
Monitor lab/diagnostics for autoimmune etiology;
complement, ESR
Monitor lab/diagnostics for obstructive etiology; KUB,
IVP
Monitor for complications:
Hyperkalemia, metabolic acidosis, uremia
CALL
Call for refractory creased urine output and
hemodynamic instability
Initiate ABC, shock management and call ready
response t4eam and MD
